Beta Backyard Kart 0.17.6

This update has a massive focus on the tires. All of the tires branded "kart" have been reworked to weigh 1/4 of the previous versions. This along with other changes to the tires means that they are significantly more realistic and also much more stable. At this point, it is still possible to fold the tires in on themselves, but it happens only during incidents that usually disable the kart anyway.

The bubble tires also got a bit of rework on them, although not nearly as in depth as the kart tires. They should handle much more predictably at speeds above 50mph now and provide much better shock absorption.

The reason I am uploading this update before finishing everything is that I noticed a major beam was missing on the welded front suspension. This was the reason behind the kart handling very differently when turning left vs right regardless of weight distribution.

I also started working on slapping the piccolina 1.5L engine on and kind of rushed it to be at least stable for this update, so expect a few issues, but it should at the very least function. It is only found on the raised rear suspension for now.

Full list of changes:

Frames:

• All:
  • slight tweaks to the precompression with beams connecting the front subframe

Engines:

• Corrected weights for all engines
• Added a new 600cc sport engine
  • Based on the Suzuki Gsxr600
  • The torque curve is based on a dyno run I found on youtube
  • The power with the high-end exhaust is based on the power ratings FSAE teams managed to get
  • Currently uses a mix of vanilla sounds as I really dislike recording the audio for new types of engines, but I will be getting a custom sound together eventually

• Fuel:
  • Added new fuel tank parts
  • Separated twin tanks into left and right.
  • Can mix and match lower and upper configurations and choose to only have a fuel tank on the right or only on the left
• Raised Rear:
  • Changed engine mount beams
• Exhaust:
  • Updated weathered exhaust texture

Suspension:

• Welded Front:
  • Adjusted precompression values further
    • The caster no longer affects the toe angle, but it heavily affects the camber. It can be compensated for by adjusting the camber for now.
  • Added a missing beam on the left arms
    • This beam was one of the primary arm beams, which meant that turning right caused the left arm to bend more than the right would, causing right turns to be more sensitive than left turns
  • Added an additional node to the center of the wheel location
    • This adds additional stability to the front wheels since there is now support directly at the wheel instead of hanging the wheel off of the hub.
• Standard and IRS:
  • Reworked the bypass shocks so they now perform much better
• Raised Rear Axle 3 Lug:
  • Added the same support node to the rear axle
• Added new suspension geometry
  • Referred to as "Alt"

Wheels:

• Significantly reduced the weight of the 8x6, 4x6, and 4x4 wheels
• Added new models for the 4x6 and 4x4 wheels

Tires:

• Significantly reduced the weight of the kart tires
• Added a new mesh to the Kart Soft tires.

Configs:

• Retuned all configs that use the welded front suspension or the kart tires
• Retuned the short course configs with the new bypass shock values

Misc:

• Animated rear axle and brake meshes for the raised rear axle
